No, Green Day is still way more relevant than Blink. Everybody knows who GD is, but my sister in middle school said that a bunch of people in her school haven't even heard of Blink. Which is incredibly sad.
I guess you're right, but I still stand by my statement that Blink has a much more dedicated fanbase, who will continue to actually buy their new albums. Green Day's fans are more composed of the people who will download a couple songs they heard on the radio.
